Identification Information

Title:

EPA Region 6 REAP Rarity Geodatabase

Abstract:

The Regional Ecological Assessment Protocol (REAP) is a screening level assessment tool created as a way to identify priority ecological resources within the five EPA Region 6 states (Arkansas, Louisiana, New Mexico, Oklahoma, and Texas). The REAP divides eighteen individual measures into three main sub-layers: diversity, rarity, and sustainability. This geodatabase contains 2 rarity layers (rarity and rarityrank) which shows the rarity of species and land cover in the Region. There are four measures that make up the rarity layer: vegetation rarity, natural heritage rank, taxonomic richness, and rare species richness. Each cell in the final rarity grid has a score of between 1 and 100 based on the average of the four measures. Cells with higher scores represent areas that have the most rarity. Cells with lower scores represent areas that have the least rarity. In the rarityrank grid, the cells are placed into the following 5 groups based on the score: 1 (top 1% of scores), 10 (top 10% of scores), 25 (top 25% of scores), 50 (top 50% of scores), and 100 (all the rest of the scores). See each individual layer for more detailed metadata.

None. Please check sources, scale, accuracy, currentness and other available information. Please confirm that you are using the most recent copy of both data and metadata. Acknowledgement of the EPA would be appreciated.
